Bell High and South Carleton High – Final Day

Today the students conducted behaviour experiments using the animals they collected throughout the week.  Each pair of students did one of five possible experiments: testing the effect of temperature on the feeding rate of barnacles, determining if size affects the flipping rate of sea stars and sea urchins, measuring the strength of different echinoderm tube feet, looking at the osmoregulation capabilities of different intertidal species, and seeing if different crab species are attracted or repelled by light.  The pairs did a great job completing their experiments and now just have to explain their results, some that were very different than they had hypothesized. 
 
This beautiful, sunny afternoon the group walked into St. Andrews to see the town and shop for souvenirs.    
 
The last activity of the trip for the students will be a bell ringer quiz to see just how much information they absorbed throughout this week of marine immersion.  I hope they are pleasantly surprised!
 
This evening the group heads out on the big red bus, with Ray behind the wheel.  May you have a safe journey!  Come back and visit us again soon!
